A giant Minecraft book with a spine...

A giant Minecraft book with a spine measuring 100 blocks long with the words Rainbow City along the spine. Each letter should be at least 5 blocks wide and each a different colour in the order of a rainbow while city is in white. The book should lay closed with the title on the cover. Perched on the book is a monarch butterfly with rainbow colours. The wings should be parted slightly as the butterfly rests on the book cover with the wings being at least the size of the book cover
